Drop your video in
Drag and drop any MP4, MOV or WebM file into the tool above. It never leaves your browser — no upload, no queue, no account.
Lock in 100 MB
The 100 MB target is pre-selected. VidSizer reads your clip's duration and computes the exact bitrate needed — no guessing with Low / Medium / High sliders.
Download under the limit
The output is measured and re-encoded until it's provably under 100 MB, with a 6% safety margin, then downloads straight to your device.
When 100 MB is the right target
20 MB is perfect for a 30-second Discord clip — but squeeze a 10-minute recording into 20 MB and the math turns brutal. 100 MB gives you 5× the bitrate budget: a 10-minute video at 100 MB holds clean 720p where 20 MB would force mushy 360p.
It's also the sweet spot under caps that sit above email limits: course uploads, portfolio sites, and sharing services that accept “up to 100 MB”. Set it, get a verified file back, move on.

FAQ
How do I compress a video to exactly 100 MB?
Select the 100 MB target above and hit Compress. VidSizer measures your clip's duration, computes the precise bitrate, and re-encodes once more until the output is provably under 100 MB.
What quality will a 100 MB video have?
Plenty of headroom: several minutes at crisp 720p, or shorter clips at full 1080p. The tool shows its planned output (resolution and bitrate) before you encode.
Is my video uploaded anywhere?
No. Everything runs in your browser. No upload, no account, no watermark.
